The FizzBuzz example gave us an good overview.
Arguments by reference
We can also pass parameters by reference. This enables us to change the variable with in the function.
/reference.lm
str sa( where:ref < str > ) { print( "in SA ", where, "\n" ) where = "sa" print( "in SA ", where, "\n" ) } where: str = "global" print( "in global ", where, "\n" ) sa( where ) print( "in global ", where, "\n" )
Compiling and running would give us:
in global global in SA global in SA sa in global sa
